The actor was discovered alone in the room shortly after noon, with responders arriving at the scene discovering a "spoon with drug residue and a used hypodermic needle." They also found 2 empty champagne bottles and glasses.

The corner lists Monteith's official cause of death as "mixed drug toxicity, involving intravenous heroin use combined with the ingestion of alcohol," though also notes, "had a history of illicit drug use with intermittent periods of rehabilitation and of abstinence from drugs."
